Conﬁguring the Adapter 3-7

Resetting the Adapter

Changes to switch settings on some adapter parameters require that you reset the adapter before the new settings take effect. You can reset the adapter by cycling power to the drive or by using the following parameter:

• Set the Parameter 09 - [Reset Module] to Reset Module:

ATTENTION: Risk of injury or equipment damage exists. If the

adapter is transmitting control I/O to the drive, the drive may fault when

you reset the adapter. Determine how your drive will respond before resetting a connected adapter.

A Adapter

Devices such as drives, controllers, and computers usually require an adapter to provide a communication interface between them and a network such as RS-485 DF1. An adapter reads data on the network and transmits it to the connected device. It also reads data in the device and transmits it to the network.

The 20-COMM-S adapter is an adapter that connects, PowerFlex drives to a RS-485 DF1 network. Adapters are sometimes also called “cards,” “embedded communication options,” “gateways,” “modules,” and “peripherals.”

B Block Check Character (BCC)

A technique for error detection in data communications. A character is added to a transmission block, which is compared with a second BCC computed by the receiver to determine if the transmission is error free.

C Controller

A controller, also called programmable logic controller, is a solid-state control system that has a user-programmable memory for storage of instructions to implement speciﬁc functions such as I/O control, logic, timing, counting, report generation, communication, arithmetic, and data ﬁle manipulation. A controller consists of a central processor, input/ output interface, and memory. See also Scanner.

Glossary

Cyclic Redundancy Check (CRC)

A commonly used technique for error detection in data communications. A polynomial algorith is performed on the data, and the resultant checksum is appended at the end of the frame. The receiving device performs a similar algorithm.

D Data Rate

The data rate is the speed at which data is transferred on the RS-485 DF1 network.

Each device on a RS-485 DF1 network must be set for the same data rate. You can set the RS-485 DF1 adapter to 1200, 2400, 4800, 9600,

19.2K, or 38.4 kbps.

Glossary-2

Datalinks

A Datalink is a type of pointer used by some PowerFlex drives to transfer data to and from the controller. Datalinks allow speciﬁed parameter value(s) to be accessed or changed without using explicit messages. When enabled, each Datalink consumes either four bytes or eight bytes in both the input and output image table of the controller. The drive determines the size of Datalinks.

DF1

An Allen-Bradley datalink layer protocol that combines features of subcategories D1 (data transparency) and F1 (2-way simultaneous transmission with embedded responses) of ANSI x3.28 speciﬁcation.

DPI

DPI is a second generation peripheral communication interface used by various Allen-Bradley drives and power products. It is a functional enhancement to SCANport.

DPI Peripheral

A device that provides an interface between DPI and a network or user. Peripheral devices are also referred to as “adapters” and “modules.” The serial converter and PowerFlex HIM are examples of DPI peripherals.

DPI Product

A device that uses the DPI communications interface to communicate with one or more peripheral devices. For example, a motor drive such as a PowerFlex drive is a DPI product. In this manual, a DPI product is also referred to as “product” or “Host.”

DriveExplorer Software

DriveExplorer software is a tool for monitoring and conﬁguring Allen-Bradley products and adapters. It can be run on computers running Microsoft Windows 95, Windows 98, Windows NT (version 4.0 or higher), Windows CE (version 2.0 or higher), Windows ME, Windows 2000, and Windows XP operating systems. DriveExplorer (version 2.02 or higher) can be used to conﬁgure this adapter and PowerFlex drives.

F Fault Action

A fault action determines how the adapter and connected product act when a communications fault (for example, a cable is disconnected) occurs or when the scanner is switched out of run mode. The former uses a communications fault action, and the latter uses an idle fault action.

Glossary-3

Fault Conﬁguration

When communications are disrupted (for example, a cable is disconnected), the adapter and PowerFlex drive can respond with a user-deﬁned fault conﬁguration. The user sets the data that is sent to the drive in the fault conﬁguration parameters (Parameters 14 - [Flt Cfg Logic] through 23 - [Flt Cfg D2]). When a fault action parameter is set to use the fault conﬁguration and a fault occurs, the data from these parameters is sent as the Command Logic, Reference, and/or Datalink(s).

Flash Update

The process of updating ﬁrmware in the adapter. The adapter can be ﬂash updated using the Xmodem protocol and a 1203-SSS Serial Converter (version 3.001 or higher).

H HIM (Human Interface Module)

A device that can be used to conﬁgure and control a PowerFlex drive. New HIMs (20-HIM-x) can be used to conﬁgure connected peripherals.

Glossary-4

Hold Last

When communications are disrupted (for example, a cable is disconnected), the adapter and PowerFlex drive can respond by holding last. Hold last results in the drive receiving the last data received via the RS-485 DF1 connection before the disruption. If the drive was running and using the Reference from the adapter, it will continue to run at the same Reference.

I I/O Data

I/O data, sometimes called “implicit messages” or “input/output,” transmit time-critical data such as a Logic Command and Reference. The terms “input” and “output” are deﬁned from the scanner’s point of view. Output is transmitted by the scanner and consumed by the adapter. Input is transmitted by the adapter and consumed by the scanner.

L Logic Command/Logic Status

The Logic Command is used to control the PowerFlex drive (e.g., start, stop, direction). It consists of one 16-bit word of input to the adapter from the network. The deﬁnitions of the bits in this word depend on the drive.

The Logic Status is used to monitor the PowerFlex drive (for example, operating state, motor direction). It consists of one 16-bit word of output from the adapter to the network. The deﬁnitions of the bits in this word depend on the drive.

N Node Address

A RS-485 DF1 network can have as many as 255 devices connected to it. Each device on the network must have a unique node address from 0 and

254.

Non-Volatile Storage (NVS)

NVS is the permanent memory of a device. Devices such as the adapter and drive store parameters and other information in NVS so that they are not lost when the device loses power. NVS is sometimes called “EEPROM.”

P Programmable Controller Communications Command (PCCC)

PCCC is the protocol used by some controllers to communicate with devices on a network. Some software products (i.e., DriveExplorer and DriveTools 2000), also use PCCC to communicate.

Ping

A ping is a message that is sent by a DPI product to its peripheral devices. They use the ping to gather data about the product, including whether it can receive messages and whether they can log in for control.

PowerFlex 7-Class Drives

The Allen-Bradley PowerFlex 7-Class family of drives include the PowerFlex 70 and PowerFlex 700. These drives can be used for applications ranging from 0.37 kW (0.5 HP) to 3,000 kW (4,000 HP). All PowerFlex 7-Class drives implement DPI, allowing them to use the 20-COMM-S RS-485 DF1 adapter.

Programmable Controller

A solid-state control system that has a user-programmable memory for storage of instructions to implement speciﬁc functions such as I/O control, logic, timing, counting, report generation, communication, arithmetic, and data ﬁle manipulation. A controller consists of central processor, input/output interface, and memory. A controller is designed as an industrial control system.

R Reference/Feedback

The Reference is used to send a Reference (for example, speed, frequency, torque) to the product. It consists of one word of input to the adapter from the network. The size of the word (either a 16-bit word or 32-bit word) is determined by the drive.

Glossary-5

Feedback is used to monitor the speed of a product. It consists of one word of output from the adapter to the network. The size of the word (either a 16-bit word or 32-bit word) is determined by the drive.

S Scanner

A scanner is a separate module (of a multi-module controller) or a built-in component (of a single-module controller) that provides communication with adapters connected to a network. See also Controller.

Status Indicators

Status indicators are LEDs that are used to report the status of the adapter, network, and drive. They are on the adapter and can be viewed on the front cover of the drive when the drive is powered.

Glossary-6

T Type 0/Type 1/Type 2 Control

When transmitting I/O, the adapter can use different types of messages for control. The Type 0, Type 1, Type 2 control events help Allen-Bradley personnel identify the type of messages that an adapter is using.

Transaction Number (TNS)

A 2-byte ﬁeld in a DF1 message packet that is used in combination with the SRC (source node of the message) and CMD (command code) bytes to uniquely identify every message packet. The TNS is typically incremented each time a new DF1 message is sent. The reply message will contain the same TNS value.

Z Zero Data

When communications are disrupted (for example, a cable is disconnected), the adapter and drive can respond with zero data. Zero data results in the drive receiving zero as values for command data. If the drive was running and using the Reference from the adapter, it will stay running, but at zero Reference.
